次の英文を読んで、 問 1 ~ 問8に答えなさい。 (配点50点) Inspired by fierce family battles for the last remaining piece of cake, a team of three high schoolers in southwestern Japan's Oita *Prefecture have invented a device that cuts round cake and pizza evenly, no matter how many pieces are sliced, and their creation won the top prize in the prefecture's invention contest in 2021. The three students are members of the industrial technology club at Oita Prefectural Kunisaki High School. Their clever invention to solve a daily life problem with a flexible *2mindset won the governor's award in the competition and is gathering attention. Twelve students in the electronics department of the school ( 1 ) to the industrial technology club, which has continued to submit works to the invention contest for about 40 years. Five of their creations won prizes in the high school division of the 2021 edition of the competition that was launched in 1941. The top prize-winning device, whose name translates to "Let's kindly divide it up," was invented by second-year students Wataru Onoda, 16, Rinto Kimura, 17, and third-year student Mitsumi Zaizen, 18. It was inspired by bbattles for birthday cake in Onoda’s family. He needed to defeat his rival two sisters in games of rock-paper-scissors to get the last remaining piece because the cake was always cut into eight pieces despite his family having seven members. Based on Onoda's idea to equally divide a cake into seven pieces, Kimura created a drawing and computer program to precisely make parts for the device. While Zaizen could not be involved in the actual production due to preparations for her university entrance she created a video for the presentation, using her experience of winning a prize in the competition for two years in a row. exams, (2 ) a two-month trial and error process, the device was completed. When a cake or pizza is placed on a turntable made with a laser beam machine, it can be cut evenly into
